Bond Arms Barrel Features The Bond Arms replacement barrel chambered in .45 ACP is machined to close tolerances for reliable chambering and consistent accuracy in this 3.5 inch configuration. This mid-length barrel splits the difference between Bond Arms shorter concealment barrels and its longer target-length options offering a balance of sight radius and compact size. The matte stainless finish provides a non-reflective surface that resists fingerprints and holds up well to repeated carry and handling. Running .45 ACP through this platform gives owners a hard-hitting widely available defensive cartridge. Because this barrel fits any original Bond Arms derringer frame owners can add .45 ACP capability to an existing pistol without the cost of a new firearm. This interchangeability lets shooters build a versatile Bond Arms setup that adapts to different carry and range scenarios. Bond Arms has built its reputation on this rugged American-made barrel-swapping system across its derringer lineup. For owners wanting a mid-length .45 ACP barrel with a durable matte finish this is a solid choice.
